' Application filed July to, 1912. Serial No. 710,719.

Be it known Ltha-t I, STARLING KILGORE, a citizen of the United States, residing at Crosby, in thecoun'ty of Harris and State of Texas, have invented pertain new and useful the following is a specification, reference had to-the accompanying drawings. This invention relates to spring wheel's and has for its object to provide a wheel of this character wherein a maximum of resiliency or shock absorbing power is obtained, with the employment 0 com aratively few elements, whereby great 'ddra ility and elficiency in "operation is also obtained. A further object of the invention resides in the provision of a spring wheel having a plurality of spokes each consisting 'of teleon the spoke sections between the rim and hub of the wheel and normally holding the spokes'in distended position, and additional lateral-strains upon the wheel in the turning movement thereof or when the same strikes obstructions 1n the road. a

With the above and other objects in view as'will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter' fully-describe and claim. a

' For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which- Fl ure 1 is a side elevation of aspiring whee constructed in accordance with the present invention; Fig. 2 is a section taken on the line 22of Fig. 1; Fig. 3 is a detail longitudinal section through the engaged ends of the bracing spoke sections. Fig. 4 is an enlarged detail perspective view of one ofthe bracing spoke sections.

Corresponding and like partsare referred to in the following description and designated in the accompanyingdrawing by like reference characters.

Referring in detail to the drawing 5 designates the hub of the wheel and '6 the rim pivotally connected as shown at 8. A plurality of inner spoke sections 9 are pivotally mounted at one of. their ends centrally upon the load thereon,'the main s V ically engaged at their outer ends in the e sections 7. Coil springs 10 t'u'bular .spo

sections 71and -9 and bear surround the spoke against the hub and rim of the wheel at their v sinner and outer ends respectively. Improvements in/Spri'ng-Whe'els, of which Uponeach end of the hub 5' an annulus 11 Patented Dec. 10, 1912.

is secured and is provided with a plurality of pairs of spaced ears 12 between which the inner. ends of the sections 13 of the bracing pivotally mounted. These brac ing spokes are arranged upon each sideof spokes are the main wheel spokes and include the outer sections 14 which are pivotally mounted at their outer ends as at 15 upon the rim 6 of the wheel. The inner ends of these sections .14 of the bracing spokes are loosely disposed through the loops or elongated eyes 1 6 upon the outer ends of the inner spoke sections 13.

By means of the above construction it will be readily observed that in the downward movement of the wheelhub by pressure of below the horizontal axis 0 the hub will move into the tubular spoke sections 7, the springs 8 being placed under compression. In this movement of the hub, the enga ed ends of the bracing spoke sections 13 M1514 slide freely upon of the bracmgspokes it will be observed are disposed at an angle with relation to each other and out of the plane of the main wheel I Thus the bracing spokes upon one.

spokes. side of the wheel and above the plane of the hub will bind on each other at their engaged ends and imit the compression of the coil springs 10, thus obviating liability of breakage of main s okes of lateral strains,-which would 'otherw1se' devolve thereon in the turning movement of the wheel.

-The rim 6 of the wheel is preferably of channel form in cross sectionand is adapted to receive the tire 17. This-tire consists of a continuous closely coiled steel-s ring which is secured to the rim of the whee at intervals by means of screws or bolts,--.indicated at 18. This spring tire renders the-wheel noiseless in its movement, and greatly increases the shock absorbing qualities thereof. A tire of eliminated.

From the foregoing it is thought that the construction and manner of operation of my improved spring wheel will be clearly under each other. 'These sections oke sections 9 Y the same and also relieving the stood. As. thesame consists of comparatively few elements of simple construction,

- it will be obvious that the entire wheel can be produced at small cost. It is of course obvious that the sizeand strength of the springs 10 upon the wheel spokes will be reg-' ulated in accordance with the weight to be sustained by the wheel. It will further be understood that while I have shown and described the preferred construction and arrangeinent of the various elements, the inven- -tion is susceptible of considerable modification without departing from the essential features or sacrificing any of the advantages thereof.

Having thus described the invention what is claimed is:

In a spring wheel, the combination with the wheel hub and rim, of a plurality of te1e Copies of this patent may be obtained m scopically engaged spoke sections carried by the hub and rim respectively, anda plurality spokes of the wheel, the opposed ends of said I bracing spoke sections being slidably engaged with each other.

. In testimony whereof I hereunto aflix my signature in the presence of two witnesses. STARLING KILGORE. Witnesses: I
